[Particles] - Child Particle Not Aligning with Parent

[-Archmage-]

I have a main projectile, and then a child projectile, and the child particle doesn't line up with the parent, and by how much it doesn't line up seems to depend on direction.
I've tried switching the 'relative' tags every which way on the parent and child to no effect.

I've only been able to get child particles working properly with splashes because there is no initial offset required.

Can you provide an example ? Ideally a whole techtree showing the problem maybe ?

Sure.
